The temperature of agent is all relatively low, and coal dust need to be sent into burner by way of pneumatic conveying or water-coal-slurry, and needs to set on pipeline
A series of valve (such as coal dust angle valve, triple valve, core flowmeter) is set to guarantee its stability being continuously conveyed.It also needs simultaneously
The cost of setting igniter burner and startup burner in gasification furnace, these pipe valves and burner itself is very high, cost
The sum of nearly equivalent to gasification furnace body cost more than half, while its maintenance cost is high, and the replacement cycle is short.
Utility model device to seam road is directly sent from one section of fluidized-bed gasification furnace, and centre is not necessarily to any control
Valve processed, and it is high because carrying out temperature degree, it is not necessarily to igniter burner and startup burner, directly from the gasification burner tip 5 among this burner
Being passed through oxygen can burn, and can save many costs compared to traditional technology.Simultaneously because come from one section of gasification furnace the tolerance of gas compared with
Greatly, as long as soon as the normal gasification reaction of section gasification furnace can be maintained, the raw gas for reaching this burner is more stable, temperature,
The fluctuations such as pressure, tolerance are all smaller, are conducive to stablizing for gasification reaction and carry out.
It is in swirl shape outside the eddy flow volute 1 of the utility model high-temperature burner, is revolved at 1 internal structure of eddy flow volute one
Circulation road can make the motion profile of raw gas be changed to downward spiral by moving along a straight line, and increase coal gas in downstream airflow bed gasification furnace
In residence time, and import raw gas is made to be sufficiently mixed and react with the gasifying agent of gasification burner tip 5, finally along 9 row of gas outlet
Out.In the process, the solid granulates in coal gas are thrown toward gasification furnace wall surface because of the effect of centrifugal force, make water-cooling wall dross effect
More preferably, screw can also make the mixing of raw gas and gasifying agent more uniform, enhance gasification reaction effect.
